The present invention pertains generally to shores tor use in building construction. More particularly the nivention relates to metallic brackets which .are connected -to the upper 5 ends of shores.

@ne object or the invention is to provide a head bracket for a shore, which is adapted be secured ixedly in place and embodies at one side thereof .a vertically movable plate 1g which is `adapted to be shifted upwardly abo'vefthe bracket yproper and then nailed or s-cabbed either directly to. a Stringer or joist lto hold the shore in its operative positionfor to a cross bar to form a. bearing area of the i desired length.

Another object of the invention is the provision of a socket or recess in the bracket which is adapted to receive a plate; on the lower end ot a vertical timber or bar to hold 2o the latter in rigid relationwhen it is desired to increase the .operative length 4or the sho-re. e

A'urther objectoi the vinvention is the provision of auxiliary member which is ad `oted to be avixed to the top face of the bracket and is shaped toform a cradle Whereeither centrally positioned crossbar may be heldin place to form a T-'head or an offset or overlianging crossbar may be supported to form an l--liead. i

A still further object of the invention is the provision ot means which operates in coni inction with the vertically vmovable plate to lock the auriliary'member against displacement Whenit is mounted on the bracket.

l object of the invention is to pro- Another vi de a brace structure which is in the nature of an attachment and'is adapted to be interlocked -with both the bracket and member to forni a brace 'lor supporting the overhanging extended end ot a crossbar.

Still another object of the invention is to provide a bracket which may be applied readily and quickly to thehead o'f'a shore and permits the shore to be used for practically all types of Work and in Which the construcas one of its objects, providing a bracket for the head end of a shore, which is of novel construction and is capable of being produced ata comparatively low cost and which is an improvement upon that disclosed in an application for Letters Patent of the United States filed by me August 27, 1927, Serial No. 215,811.

Other objects of the invention and the various advantages and characteristics of the present construction will be apparent from a consideration of the following detailed description.

The invention consists in the several novel fea-tures herein set forth and more particu-- larly defined by the claims at the conclusion hereof.

` The' invention is exemplified in connection with ashore 11 which is adapted for use in building 'construction' aiidis made; of-'an 'n elongated beam orxtimber. The upper end of the shoreis cut away from side to side to form a'pair oftimber-members 12 Aand an intermediate open-top chamber 13. f lThe lower end of the shore'lll is provided ywithany suit- ,able'adjusting means(not'shown) so tha't'the vshoremay be positioned Yvertically'to support vrtheV head thereof at any desired elevation.

lThe head, whichV forms the subject matter of the' present'invention, embodies a bracket 14` wh-i'chis formed Vof1a 'onepiece casting and comprisesu al pairl of oppositelyy facingV and parallel side walls 15. and a pair of oppositely facingfa'nd parallel fend walls 16'. Y The wallsA of the bracket forma rectangular so'ckf et 17 which yis open at thetop .and bottom thereof andiits around the upper ends of thetimber-members ,12; The bracket :is arl ranged so that the 'upper edges of the walls A15u-'and' 16 areflush with the topbfaces .of the L ktimber-membersY 12. 1t" is `fiXedly held in "place by bolts 18Vwhich lextend through the end walls 16 and the *upper eIlQlSO Said Cimdisconnected from` the bracket. The lower bermembers. Therev are fpreferfably two `bolts associatedy with each timber-member Y l and these bolts are arranged sothat the lheads thereof fitl against the end walls and thelnuts 5 are located in thechamber 13. ln addition` to the walls 15 and 16, the'bracket comprises`- a pair of l'horizontal and longitudinally pro-V jecting arms 19 and 2O.Y TheA latter are Vformed integrally with the end walls'l and embody topbea-rifng surfaces v'which are 'flush with" the top 'of the-socketfl. Triangular webs 21 serve to brace or reenfor'ce the arms;vl These webs areformed inteofrally withand"necton'with a stringi I. o' th .v '1, underlie the side margins obf the armsand be rdols e mms L9 are in the *naturel of. continuations, of theliside walls '15; The top bearing surfaces' of.V

"fthe rarmsV may be used tofflt directly against the bottom party of afstringer orjoistfor theyj may be secured to ai relatively short'cross- 1 bar 22, as shown in .Figure 7 sothatsaid e crossba-r forms a supporting surfacey or plane headat the top.v of the shore." Thev arms-19` and are providedv withcircularfholes or apertures A28 throughwhich nails maybe driven to securethe shore to the Stringer or joist or to affix the crossbar 22 in place on the top of the bracket.v When theV bracket is usedwith thecrossbar 22, they shore -is adapt# ed for use in connection'with work that needs 1 only a small `supporting surface. Y

To form' an abutmentof side member,V when thebracket is used against a joist or f `stringer orto support: the crossbar 22, a

rectangular plate 24 is provided. This plate fits against the timber-members 12 adjacent one of the side walls 15 and is slidable vertically so that the upper end thereof may be shiftedvintoits operative position above the bracket 14C.VH The lower end of the plate is'convfined vto sliding movementjonly by a U-sh'aped strip 25 which is located in the chamber 13 and vissecured to the inner face of the plate 24 by aistud 26.A Saidstrip is provided With outwardly projecting ears'27 whichare slidable in vertical grooves V28 in the inner and opposed `faces kof the timber-members A12. .The'uppe'r end of the plate extends through Yaslideway 29Vwhichl is formed .by an oset vwall portion 80. The latter'isfa partof and constitutes the maj or portion'ofthe side wall lfwhichgis associated Awith the: plate 2.4.

The slideway 29 and the'U-shapedstrip 25 together constitute means whereby the plate is slidably' held inplace so that'fit maybe shifted vertically into its operative position.

'TheY upper end Vof the 'plate 24 is provided withc'i'rcular holes or apertures' 31 for the V`insertionfofl nailsor screws 32 whereby the l*plate may be secured in place.V The head of 'the'stud 26 projects outwardly va sufficient i distance to strike against'thelower edge of the offset lwall portion 29an`d thereby limit 'the upward movement of theplate-24 so that Y the latter isfpreventedfrombeing removed or ends V'of theY grooves. 28 form VVabutments againstfwhich'theears 27 strike to limit the Vdownward'movement ofthe plate?. rIfhe said lower ends vof the grooves are so .positioned that when-.the plate isin its inoperative ordownward position the upperend thereof is beneath thev bearing surfaces ofthe arms 19 and 2O.V 'A characteristic and an'aidvanf" vtage of mounting the plateinthernanner setforth is'v that thebracket may be used independently'wof or` inconjunction Awith rthe plate.V When the bracket isv to be used inrcon- Y and. 2() are arrangedin a supporting position maybe driven through the holes 23 into/the bottom Vpart of the stringer.y Vhen the l bracket-14 iste be used with the'crossbar 22 vto form a plane' head for'the shore, the paris placed upon-.the arms and against the plate and is ithen nailed in place.

1n lsome instances it is desirable to use a T-headorL-head type of crossbar 33 inconnection with lthesh'ore (see Figures 1-2 and 5). Since the `top bearing surfaces of the arms lband 2O are small and Wouldnot serve to .provide the proper supporting area -for an extended :bar ol `this character, an -auXiliary member 34 is provided. This member operates to increase the supporting area ot the bracket 14 and is -shapedto form-a cradle :in

which the crossbar 33 is positionedand held.

"bar 33 in piece. vausi-hairy member-ware held :in connected 're- Said-.inember34 is iormedofa one-piece castingand comprises Va longitudinally elongated bottoni wall l35 which is adaptedto underlie the bottonrotv the crossbar 33,-and a pair of side walls 36. The latter, ftogether `with the bottom Wall357 forma chamber in v.which the crossbar flits snugly and :is held. The member 34 is adapted to rest vdirectly upon the vtop bearing surfaces-of the arms 19 and 20 and the ends thereof fproject outwardly of said arms. The `bottom vwall 35 is rprovided with circular holes .or apertures .37 `through which nails 'maybe driven t`o-secure the cross- The bracket 14 and the cent the `base ot said recess. The plate 24 adapted to be shifted upwardly so vthat the'iipper-end thereotextends through this slot and into lthe recess and .forms :an eloment or instrumentality whereby `the inember is held against transverse displacement. To prevent-the-member 34 froin-beinglslidztoo farV forward during-the connectingr operation. and so that the slot 42 is :out of registry with 'the elideway 29, a .pair of Alugs 43 are provided. These lugs are formed integrally with anddepend from vthe` wall portion 40, as shown in Figure (ha-nd engage the arms 19 and 20 tocenter properly `the slot 4Q. lVhen the plate is operative to lock the member 34 in place, the extreme upper end thereof is positioned above the side walls 36 with the result that nails 32a may rbe driven into the Vcrossbar 33 lt"iri"o'u..frh the holes '31 to form a positive locking connection between the va- '.rlons elements. When the ci'ossbar 33 -is used to form a'T-head for the shore. it is positioned ii centrally with respect to the member 34.

T{Pill-'ien the crossbar isftobeused as an L-"head,

-continuation ot the .of the bai` 45 and `is provided with a .pair of it is positioned so thatlone end thereof `projects turther outwardly than the othei,fthat is, Vin odset or overhanging relation. The member 34 exemplifies means of an improved character 4for increasing the supporting area ofthe bracket 14 so that said bracket may be used readily in connection with either a T or L-'head crossbar. The guides 38 exemplify slide means whereby the member and bracket may be connected together'.

In building,r Construction, the L-head type of shore is `generally used whore it is necessary lto support a platform or staging alongside 'concrete form. So that it will not be 'necessary to extend the auxiliary member 34 so thatit-is bulky and excessive in weight, a brace structure is provided. This structure is in the natureot' an attachment and is adapted to be interlocked both with the bracket and the .member 34. It consists of a. horizontalV bar 45 the inner end ot which is'bent to form an offset hook 46. The latter .is vadapten to pass through a transverse slot 4T inoneend of the bottom wall 35 so that it assumes a position wherein the hook proper `underlies the port-ion of said Wall immediately inwardly of the slot and the part of the bai' adjacent the vhook overlies a depressed .portion or strip 43. vSaid strip yis formed integrally with the bottom wall f adjacent and immediately outwardly of the -slot 47 and operates `in conjunction with a pair of parallel ilugs 49 to hold ythe inner end of the bar against transverse movement. In

-addition to preventing` transverse ymovement ot the barythe strip 43 cooperates with the -outeror curved part otthe hook to prevent.

longitudinal movement. The upper tace of the bar is substantially flush with the top face ofithebottom wall 35 so that it forms a supporting surface which is provided for the crossbar 33. A lug,r 50 is connected by rivets 51 .to the outer end integral downwardlyY projecting lingers The latter are adapted to receive adiagonal brace or compression member 53 which is T- shaped in cross section and comprises a Aflange 53aand a web 53D. The inner or 'lov-.fer end vof the brace-member is supported .from

the bracket 14 by a suspension or ltension bar 54. The lower end `of this last mentioned bar is riveted. to .a lug 55 which is I provided with apair of upwardly extending lingers 56. The iiange of the T-shaped meinber 53 abuts against the lug 55 and the web portion 'lits between the lingers 56. A, bolt 5? extends through a slot 58 in the lower end -of theweb and 'operates to hold ythe bars 53 and 54 in connecte-d relation, more particularly `when they are Vnot yin use. The slot-58 is 'elongated fto permit the ybraco-inf-xmhor to be folded against the 'bar when it is not in use. The upper end o'lfthe 'bar 54 is provided withvafslot 59 to reccivea fhook .60 i

that bears the slot 47. lThe hook and slot connection between the upper end of the bar 54" and the bracket constitutes means which permits the brace structure tovbe removed from the .bracket .when it-is `not used. A. slot Y Y Insome instances the adjusting device at thel lower end of the shore is'not capable of positioning the head' at the proper elevation vand it is necessary tok use anextension timber 63 ,toi increase the operative length of the shore. This timber is held in place, as shown in4 Figures 9 and 10, bythe plate 24 land a Vsecondplate 64 which is attached to the lower end of the extension timberand is heldinI a slideway 65.1.The latter is formedby an olf- `set Wall portion: 66 VWhichis similar to and opposite theoset Wall portion 40. A slot 67 is' formed 'inthe bottom Wall 85 adjacent thev slidevvay so that the distal end of the .plate 64 on the .extension timber mayeXtend against the timber-members 1 2. f The head construction herein disclosed and consisting of the) bracket 14, the auxiliary Ine'mber andthe brace structure may be f vinanufactured at a comparatively lowcost n and adapts the.` shore for practically univerf'sal application. It is eXtrem-ely simple and permits of ready and quickY assemblage.
